Chemistry topics first played a modest role in the Album. This changed only after the Amsterdam chemistry teacher G. Doyer van Cleeff joined the editorial board in 1886 see Chemisch Weekblad, 13 (1916), 856-8. 

In 1919, in the journal Chemisch Weekblad, H. J. Prins reported the reaction of alkenes with formaldehyde in the presence of acid to give dioxanes, diols, and unsaturated alcohols.3-5 The reaction was apparently discovered by Kriewitz in 1899,1,2,6 but Prins carried out the most thorough initial investigation of the reaction and hence it carries his name.6 In one example from this study, Prins found that styrene 6 reacted with formaldehyde 2 in the presence of sulfuric acid to give 1,3-dioxane 7, allylic alcohol 8, and diol 9. When the reaction was carried out in glacial acetic acid, esters of this acid were the primary products.3-5...
